N1 (Glitter) is a formula Ned Gorski came up with by modifying and combining a couple of other formulas, as Winokur 24 - glitter, D1 (Glitter) etc. It burns a bit more slowly than the D1 (Glitter) and the tail is a longer, slightly more delayed glitter, which sparks like a Senko Hanabi sparkler. This formula has a longer burn time, comets made with it can be pumped about 2/3 as long as their diameter. So, it's a bit more economical to make and use
This composition is best suited for pumped and rolled stars. Glitters are moisture sensitive and cut stars usually require a moisture content larger than the one recommended for glitters. Mixing takes place as follows: If necessary, the chemicals (except the aluminum) are prepared individually with a roller, coffee grinder etc. They are then blended by hand adding the aluminum and passed through a mixing screen several times. You can also integrate the ingredients via ball milling; in this case the aluminum must not be added before milling and has to be integrated by hand when milling is complete. In the case of pumped stars the mix is dampened using a maximum of 10% by weight of 90% water/10% alcohol (with 2% boric acid dissolved in it) and formed into stars.
